3376: Fix a common false-positive type mismatch r=matklad a=flodiebold
E.g. for `&{ some_string() }` in a context where a `&str` is expected, we
reported a mismatch inside the block. The problem is that we're passing an
expectation of `str` down, but the expectation is more of a hint in this case.
There's a long comment in rustc about this, which I just copied.
Also, fix reported location for type mismatches in macros.

rust-analyzer is an experimental modular compiler frontend for the Rust language. It is a part of a larger rls-2.0 effort to create excellent IDE support for Rust. If you want to get involved, check the rls-2.0 working group:

Language Server Quick Start
rust-analyzer is a work-in-progress, so you might encounter critical bugs. That said, it is complete enough to provide a useful IDE experience and some people use it as a daily driver.
To build rust-analyzer, you need:
- latest stable Rust for the language server itself
- latest stable npm and VS Code for VS Code extension
To quickly install the rust-analyzer language server and VS Code extension with
standard setup (code and cargo in $PATH, etc), use this:
# clone the repo
$ git clone https://github.com/rust-analyzer/rust-analyzer && cd rust-analyzer
# install both the language server and VS Code extension
$ cargo xtask install
# alternatively, install only the server. Binary name is `rust-analyzer`.
$ cargo xtask install --server
For non-standard setup of VS Code and other editors, or if the language server cannot start, see ./docs/user.
Documentation
If you want to contribute to rust-analyzer or are just curious about how things work under the hood, check the ./docs/dev folder.
If you want to use rust-analyzer's language server with your editor of choice, check ./docs/user folder. It also contains some tips & tricks to help you be more productive when using rust-analyzer.
